HUB-TTACHNG DEVICE.

vide a means for retaininglthe wheel on an' axle spindle without theemployment of the usual nut or cap. Y

A further object of this invention is to lessen the friction between thehub and spindle by providing a ball bearing surface, the ballsperforming the double function of reducing the friction and of retainingthe Wheel on the spindle.

Still another object of this invention is to provide a novel means forretaining the balls in their respective grooves, the means forming acontinuation of the grooves.

W ith these and other objects in view, as will more fully hereinafterappear, the invention consists in certain novel features of constructionand arrangement of parts,here inai'ter fully described, illustrated inthe aocompanying drawings, and particularly pointed out in that portionof this instrument wherein patentable novelty is claimed for certaiiidistinctive and peculiar features of the device, it being understoodthat, Within the scope of what hereinafter thus is claimed, variouschanges in the' form, proportions, size and minor details of thestructure may he made Without departing from the spirit or sacriicingany of the advantages of the invention.

.lin the accompanying drawings z--Figure l is a longitudinal sectionalview, parts being in elevation. Fig. 2 is a traiisverse seetion on theline 2 of Pig. 1. 3 a perspective of the retaining bolt.

Similar numerals of reference are employed to indicate correspondingparts throughout the several igures of the drawings.

1 designates a hub of ordinary type with "adiai threaded apertures 2 andextending inv-Jardiy from the outer surface and terminating in the bore4, and alining with aper- J tures 5 and e in the spindle sleeve l. lheapertures of the spindle sleeve are of considerably less dian'ieter thanthose of the hub for a purpose to be later explained.

The outer face of the sleeve is tapered Specification of Letters Patent.

and in its here 13 are `termed the gri'ioves 14 and 15 intersecting theapertures 5 and The spindle sleeve bore is of ya sutlicient diameter tofreely accommodate the shaft spindle El, the latter haif'ing a collar i)formed thereon, the face of which ahuts against a shoulder 1G formed onthe limer end of the spindle sleeve 7. filming with the apertures in thespindle sleeve and the grooves 14rand 15 of the latter are grooves lland 1Q formed in the spindle and accommodating one hemisphere of theball lo?, the opposite hemisphere fitting in the grooves liland 15 ofthe spindle sleeve. When the balls are in their respective grooves it isobvious `that lateral movement' of the sleeve is prevented bothoutwardly and inwardly by the balls abutting against the sides of the"grooves of the spindle and sleeve.

The screw members 17 are threaded for a portion of their length andterminate in reduced ends 18 and are provided with the usual heads atone end7 and formed in the opposite end are recesses 19. The function ofthe recess is to overlie the balls, .thereby providing an uninterruptedgroove in the spindle sleeve, the vreduced portion 18 being of adiameter to snugly lit thc apertures 5 and 6 i1; the spindle sleeve, theshoulder 20 contacting with the outer surface of said sleeve. rinotherfunction of the screw is to key the hub to the sleeve Which is obviouswhen the screw is threaded into the apertures of the hub l7 the shoulderresting onthe surface of the sleeve, the reduced portion entering intethe apertures 'and (i, and the groove or recess overlying the balls.W'ith this arrangement the hub and sleeve will revolve about thespindle, the balls perforinii'ig the function of an end nut or cap. Theaxial bore of the hub is terminally enlarged adjacent the inner cud ofthe hub as denoted by the numeral e'O, they sleeve be-.

ing provided7 adjacent .its inner end, with a shoulder il, which isadapted to engage the enlarged portion 40 of the axial' bore of the hubto limity the radial apertures of the sleeve and of the hub to positionin alinenient.

il. device of the class described comprising a hub having a taperingaxial bore terminally enlarged adjacent thc inner end of the hub; atapering spindle sleeve arranged to be inserted in the bore of the hub;the hub being provided with radial,'oppositely dise of the sleeve withthose of the hub; the

.sleeve being provided in its inner face with eireuinseribing groovesintersecting the apertures` in the sleeve; the bore of the sleeve beingenlarged at its inner end to 'forni a shoulder; a spindle arranged to beinserted into the sleeve and provided with circumseribing groovesarranged to be brought into alineinent with the grooves in the sleeve;the spindle having' its outer end flush with the outer ends of thesleeve and the hub and being provided at its inner end W/i'th a eollarar Iang-ed to be housed within'y the contour of the sleeve in theenlarged portion -of the bore thereof and to abutagainst the shoulderformed by said' enlarged portion, to aline the grooves of the spindlewith the grooves oit the sleeve; balls located in the alined grooves ofthe spindle and the sleeve; ineinbers headed to engage the outersurface' of the hub and threaded to engage the apertures in the hub; thesaid members terniinating in smooth, reduced ends to register in theapertures in rthe sleeve, the diierenee in the diameter of the portionsof said. meni v bers determining a shoulder to enage the outer surfaceof the sleeve; the inner faces of the reduced ends being recessed toContorni to the grooves in the sleeve.

Tn testimony that I claim the forgoing as n'iy own, I have heretoaffixed my signature in the presence of two Witnesses.
